UGen: An Agentic Framework for Generating Microarchitectural Attack PoCs

Microarchitectural attacks continue to evolve, uncovering new exploitation vectors in modern processors. From a defensive perspective, assessing a system's susceptibility to such attacks remains challenging. Developing functional attack implementations is labor-intensive, requires deep...

Microarchitectural Attacks on the Stack Engine

Summary Researchers from ETH Zurich have published a paper titled “One Flew over the Stack Engine’s Nest: Practical Microarchitectural Attacks on the Stack Engine.” AMD continues to recommend software developers employ existing best practices including constant time algorithm and avoid...

Valkyrie: a Response Framework to Augment Runtime Detection of Time-Progressive Attacks

A popular approach to detect cyberattacks is to monitor systems in real-time to identify malicious activities as they occur. While these solutions aim to detect threats early, minimizing damage, they suffer from a significant challenge due to the presence of false positives. False positives have ...
